Where does 909 come from?


The 909 area code started service in Southern California in 1992. It overlaps parts of four major counties, including San Bernardino, Los Angeles, Orange, and Riverside, though it’s mostly centered around the city of San Bernardino.


In 2004, many phone numbers were split from area code 909 and reassigned to the 951 area code that covers neighboring Riverside, California.

By 2017, due to an expanding population in the region, the 909 area code was nearly out of available phone numbers, with a new area code slated within the current 909 area by late 2018.

On a sunny September day, Christina Ayres lay on the sand near the Huntington Beach Pier, tanning in a pink bikini, and ticked off the things that identify a 909er...Bad clothing — " 'Jersey Shore' style," the 29-year-old explained. And meth addicts. "That's what you hear on the news."

Who uses 909?

909, of course, is used in actual telephone numbers. The geographic area the 909 area code covers is sometimes called the 909 and people who live there, 909ers.

909 can be used with pride …

… or, more often, disparagement, as residents in SoCal’s wealthier coastal communities sometimes use 909 to insult people from San Bernardino and inland Southern California more generally as “backwater” and “white trash”:
